Just because something hasn’t changed in a while does not mean there is no room to improve it further.

Putting wheels on luggage didn’t become popular until the 90’s.
Left and right shoes for your left and right feet weren’t even invented until like the 1800’s.
Stirrups, I’m sure you know were invented thousands of years after we started riding horses.

Or, probably the most pertinent example, the compound bow. Wooden compound bows exist and could have easily been made in ancient times, but they weren’t invented until 1966.
